I remember you used to be really silly, badly behaved and immature, you served your time in POW and came out a different person, you were mature and you've stayed the same since. Well done!8/10.8/10.7/10.72%

I was in PoW late 2011 and you only joined 10 months ago, lol. Had you an account before cmdbxx?

Idk about percentages xD We just compare the grade boundaries of the exam to the mark. For example, in exam paper that is 100 marks. 80 marks would be an A, 70 marks would be a B, 60 would be C, 50 would be D etc... Sometimes, the grade boundaries change if the exam paper is difficult than usual or easier than usual.
